PLOW-BEAM ATTAGHMENT.'

Specification of Letters Patent.

Patented Jan. 9, 1917.

Application filed February 21, 1914, fierial No. 820,207.

To all whom it may concern Be it known that I, the undersigned, DAVIDWALTER SWEAT, acitizen of the United States, residing at \Vaycross, inthe county of Ware and State of Georgia, have invented certain new anduseful Improvements in PlowsBe-am Attachments; and I do hereby declarethe following to be a full, clear, and exact descriptionof theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to an attachment for the beam of a plow and ismore particularly designed for use in connection therewith foreliiciently dragging the weeds, stubble or green crops sown for thepurpose of. enriching the soil, and has for one of its objects theprovision of a laterally extended curvilinear weed hook for bending overthe stubble or green crops in advance of the moldboard of the plow inorder that the same may be turned under in the furrow by the plow.

Another object of this invention resides in the provision of anattachment for a plow whereby the same may be adjusted along the beamthereof in a longitudinal direction for adjusting the same relatively tothe height of the stubble or green crops to be turned under forpreventing the exposure of the same above the plowed ground.

A further object of this invention resides in the provision of anattachment for plows for turning under green crops, etc, whereby theattachment is capable of vertical adjust.- ment for regulating the samein accordance with the depth of plowing,

These and other objects will more fully appear and the nature vof theinvention will be more clearly understood by the construction,combination and arrangement of the parts thereof as described in thefollowing specification, defined in the appended claims and illustratedin the accompanying drawings, in which,

Figure 1 is a side view of a plow showing my t ment arr ed ther on n P-erative position. Fig. 2 is a top detail view partly in section, thebeam being shown in dotted lines, showing the means by which theattachment is secured at the under side of the beam of the plow throughthe means of the hook end bolt. Fig. 3 is a front view of my device, thebeam being shown in section illustrating the position of the laterallyextending arm of the attachment and the complete means of securing thesame to the beam of the plow.

For the sake .of convenience and illustration of the adaptation of myinvention to a plow I have shown the plow in conventional-form wherein 1denotes the beam, 2 the handles, '3 the mold-board and 4: the sharethereof. At any desired point upon the beam 1 at the mold-board sidethereof is the laterally downward and slightly rearwardly extendingcurvilinear weed hook 5 of reversely curved formation provided at thefree end thereof with the rearwardly curved end 6, the curved end beingdesigned to provide a guard finger for deflecting the weed hook fromobjects which the same may come in contact therewith such as stones,trees, etc., and also to retain the growth within the body portion ofthe weed hook. The inner end of the weed hook 5 is bent upwardly toprovide the curved neck 7 approximately right angularly thereto andcontinuing from the neck 7 is'the vertically extending attaching shankor bar 8, the bar 8 being provided with aseries of alined apertures 9adjacent the upper end thereof and provides means for the verticaladjustment of the weed hook 5 upon the beam 1. Vertically disposed uponthe beam 1 at the side opposite to the attaching bar 8 is the retainingbar 10 provided adjacent the upper end thereof with the aperture 11 andthrough which aperture and one of the apertures 9 of the attaching bar 8is designed to pass the bolt 12, the head 13 of the bolt bearing againstthe outside of the bar 8 and the nut 14 of the bolt 12 positioned at theouter side of the retaining bar 10, the bolt 12 positioned upon theupper surface of the beam 1 and designed to connect the upper ends ofthe attaching bar 8 and the retaining bar 10.

For additionally securing the attachment to the beam 1 I provide thehook end bolt 15 at the under side of the beam,.t he hook end 16 of thebolt 15 embracing that portion of the attaching bar 8 adjacent theangular bent portion or neck 7 of the weed hook 5, the threaded end ofthe bolt 15 extending through the aperture 17 arranged adjacent thelower end of the retaining bar 10', and upon the projectingscrewthreaded end of the bolt 15 is the nut 18, the bolt 15 and nut 18providin means for securing the lower portions 0 the attaching bar 8 tothe retaining bar 10 at the under side of the beam 1 of the plow.

By the provision of the hook end bolt the hook 16 embraces that portionof the attaching bar 8 where the greatest stress is exer'ted, thus thehook 16 provides the'most eflicient means of securing the attaching bar8 at the under side of the beam 1 whereby the strength of the weed hookis not weakened at the point of greatest stress as the same would bewith apertures formed through the bar at this point.

I desire to state that my attachment consists of an integral structureand may be formed of any suitable material and either rounded orrectangular in cross section as desired, however, I have hereillustrated the weed hook 5 as being rounded this being the preferredform from the fact that there are no sharp edges for engaging thestubble or green crops to be turned under and thereby adding to thedraft of the plow, whereby the same being rounded in cross sectionglides easily over the upper surfaces of the bent crops, etc., withlittle or no friction and V by curving the body of the hook rearwardlythe edges of the foliage upon the ground are deflected inwardly towardthe center line of the hook and thereby facilitates the more efiicientcovering of the foliage by the mold board of the plow. And, further, inthe construction of my attachment for plows I have invented a devicewhich maybe attached to any plow now in use and by the adjustment of thesame longitudinally of the beam, as well as vertically thereon providesa device for eiiiciently regulating the same to meet all therequirements and conditions attending the use and purposes of which myinvention is designed.

While I have here shown the-. preferred embodiment of my invention Ihereby reserve the right to make such alterations and variations thereinfrom time to time as I may deem expedient and which will not depart fromthe spirit of this invention or the scope of the appended claims.

Having thus fully described my invention, what I claim and desire tosecure by Letters-Patent is:

1. In a weed hook attachment for plows, comprising an integral bar,consisting of a reversely curved body portion terminating in arearwardly turned guard finger at one end, and a vertical shank at itsother end,

and means for securing said shank upon the beam of a plow.

2. In a weed hook attachment for plows, comprising an integral bar,consisting of a vertically disposed attaching shank having a pluralityof apertures in its upper end, a downwardly and rearwardly curved neckextending from the lower end of said shank, a reversely curved bodyportion extending laterally downward from said neck, a rearwardly turnedguard finger upon the free end of said body portion, and means foradjustably attaching said neck hook upon a plow beam.

3. In a weed hook attachment for plows, comprising an integral bar,consisting of a vertically disposed attaching shank having a pluralityof apertures in its upper end, a downwardly and rearwardly curved neckextending from the lower end of said shank, a laterally and slightlydownwardly disposed body portion extending from said neck, said bodyportion being curved first rearwardly and downwardly and thenceforwardly and downwardly and having its free end curved rearwardly toprovide a guard finger, and means for adjustably securing said weed hookupon a plow beam.

4:. In a weed hook attachment for plow beams, comprising a downwardlyobliquely disposed reversely curved hook member, having a rearwardlyturned guard finger formed at its outer end, and an upstanding shankformed at its inner end, said shank having a plurality of aperturesadjacent its upper end and adapted to engage one side of said beam, anapertured plate adapted to engage the opposite side of said beam, anupper securing bolt projecting through one of the apertures of saidshank and the upper aperture of said plate, a lower securing bolt havinga screw threaded end projecting through the lower aperture of saidplate, and an angularly formed hook member at the opposite end of saidlower bolt for embracing the lower portion of said shank, whereby toadjustably secure said weed hook upon said plow beam.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
